In a northern aerospace city, seven only‑children bond like siblings and call themselves “The Big Dipper,” vowing to ace the college entrance exam and head to Beijing together. Years later only Huang Yingzi succeeds; Jiang Yi studies in the United States while the others pursue separate paths. Now, as they navigate work and adulthood, lingering questions of first love and broken dreams resurface, prompting Yingzi to seek a reunion that may finally answer the mystery of who they each loved at seventeen.
